PE Selection Logic

After you provision port extenders and power them on, the PEs come online according to the selection logic
in the scenarios described in this section.
• You may provision cascade ports for different PEs but connect the cascade ports to the same PE. In this
case, only the PE with lowest PE ID comes online. In the following example, both cascade ports 1/0 and
1/12 are cabled to the same PE. However, port 1/0 is provisioned for PE 10; port 1/12 is provisioned for
PE 20. As a result, only PE 10 comes online. PE 20 remains offline and its configured cascade port is
placed in an error state.
